*surfacespherefromthreepoints
Creates a full or partial sphere, and optionally, prepares it for immediate use within the automesher. It can also identify a region in the shape of such a sphere for the automesher to use under the mesh without surface option.

Description
Creates a full or partial sphere, and optionally, prepares it for immediate use within the automesher. It can also identify a region in the shape of such a sphere for the automesher to use under the mesh without surface option.
Inputs
- center
 - A node specifying the center.
 - radius
 - The radius of the sphere.
 - r
 - A node specifying the r vector.
 - theta_start
 - Angle at which theta starts (0.0 to < theta end).
 - theta_end
 - Angle at which theta ends (> theta start to 360.0).
 - angle_node
 - A node specifying the angle vector.
 - phi_start
 - Angle at which phi starts (-90.0 to < phi end).
 - phi_end
 - Angle at which phi ends (> phi start to 90.0).
 - angle_type
 - Defines whether the angle vector is to be theta or phi.
 
Example
To create one quarter of a sphere with a radius of 10 through using nodes 1, 2 and 3, but not create any elements:
*surfacemode 4 
*surfacespherefromthreepoints 1 10.0 2 0.0 180.0 3 0.0 90.00 0 
      The *surfacemode(4) directive tells HyperMesh not to pass the information on to the automesher for element creation.
Errors
None.
